Physical cash is more fungible than bitcoin UTXOs. Physical cash notes are almost identical except for the serial number, which doesn't have a history of previous transactions. UTXOs have a history and with the proper software can easily be traced automatically. The idea of Monero is to quite solve this exact issue. I think some solution (other than monero's) to make utxos in bitcoin more fungible will be beneficial.
